  Update: The Arduino system is fine; the only thing you have to take into consideration is the 9.54 hour rollover event, which Rob Faludi has provided an excellent solution for here. I made up a nice little over-analysis of the issue, available here.
  
  I have been wanting to make a variable-speed clock for a while, so this weekend I picked up a cheapish clock unit (thrift stores are a great source!), and played around with using the Arduino to control it. In summary, I was able to get everything going, but there are some issues with the Arduino software that are going to prevent making it a really accurate clock. Explanation, source code after the break.
